The Warden's champions, one at a time, until you drop. Read the glowing wind-up and answer it:

TAP LEFT or RIGHT to dodge when the ring around his fist turns AMBER. Every machine throws five different things and the wind-up names them: amber JAB (either dodge, or guard), red HOOK (one side only, and it goes through your guard), violet UPPERCUT (either side, also pierces), amber COMBO with a pip per link, and a washed-out FEINT whose ring never lights, thrown to spend your dodge before the real one. TAP CENTER to jab an opening. HOLD CENTER for the haymaker. HOLD the LOW strip to guard. Punches cost stamina, so pick your windows. Three bouts take the belt, then the TITLE DEFENSES never stop coming.
